  • Patent number: 9844789
    Abstract: A viscous liquid feed nozzle has a nozzle body having a thin and long hole with a front end serving as a feed port. The nozzle is used with a viscous liquid feed unit to feed a viscous liquid such as a viscous adhesive from the feed port. The nozzle has a lubricative plated layer at least on the inside and outside of the feed port. The lubricative plated layer is formed by electroless plating by immersing the nozzle in a plating tank containing a lubricative plating solution. A base end of the nozzle body may have a wide port. In this case, the lubricative plated layer is formed by immersing the nozzle body in the plating tank containing the lubricative plating solution so that the lubricative plating solution enters the wide port and by applying pressure or gravity to the lubricative plating solution in the wide port to pass the lubricative plating solution through the thin and long hole of the nozzle body and discharge the same from the feed port.

  • Patent number: 9218832
    Abstract: A method of surely removing a read/write slider from a flexure without large displacement of the slider, the slider attached to the flexure of the head suspension through an adhesive, comprises heating the slider so that the adhesive is heated through an adhered surface of the slider being in contact with the adhesive; and applying ultrasonic vibration to the slider so that the adhered surface of the slider vibrates at ultrasonic frequency with respect to the adhesive.

  • Patent number: 9070418
    Abstract: A cutting jig cuts bonding material of a terminal joint between a magnetic head's slider and a flexure's wiring terminal. A base of the jig receives the slider. A blade moves along the base and faces a front side wall of the slider in a moving direction. An upright portion of the jig is formed on the base and has a stop face that faces a rear side wall of the slider in the moving direction. The blade moves toward the slider to come into contact with the bonding material, and is pressed to the front side wall of the slider. The bonding material is interposed in the moving direction while the rear side wall of the slider is brought into contact with and is stopped by the stop face when the slider is set on the base and the bonding material is cut.

  • Patent number: 8893646
    Abstract: A liquid application apparatus applies a liquid to an objective region. The apparatus includes a trap having an opening from which the liquid linearly appears, a feeder to feed the liquid to the trap, and an operation unit to position the trap on the objective region and bring the linearly appeared liquid at the trap into contact with the objective region, thereby linearly applying the liquid to the objective region. The apparatus is capable of linearly applying the liquid in a uniform thickness to the objective region.

  • Patent number: 8773653
    Abstract: An attitude correction apparatus includes a pair of opposing laser emitters that face each other. Each of the laser emitters includes a laser oscillator to generate a laser beam, a condenser lens to emit the laser beam toward the head suspension, and galvanomirrors to adjust the directivity of an optical axis of the laser beam from a standby state toward a spot on the head suspension. The condenser lens of each laser emitter is positioned so that the directivity of the optical axis of the laser beam in the standby state disagrees with an optical path that passes through the condenser lens and laser oscillator of the other laser emitter.

  • Patent number: 8689429
    Abstract: A method of reworking a head suspension removes a slider from the head suspension by pressing a blade from a first side toward a second side in a longitudinal direction of the slider to solder ball bonding, stopping the second side of the slider in the longitudinal direction with a holding mechanism, and forcing the blade to bite and cut the solder ball bonding to remove the slider from the flexure. The solder ball bonding is cut without applying extra force to components of the head suspension except the slider. The method improves product yield.
